COMMISSIONED REPORT Summary Surveillance of priority terrestrial invertebrates in Scotland Commissioned Report No. 609 Contractor: N.A. Littlewood & J.A. Stockan Year of publication: 2013 Background Scottish Natural Heritage has been asked by Scottish ministers to implement a strategy for the surveillance of priority habitats and species in Scotland. This report covers the development of such strategies for 55 species of non-marine invertebrates and draws extensively on expert comment from consultees with specialised knowledge of individual species covered. For each species, a report was written to present background information about the status of the species in Scotland together with issues relevant to surveillance, such as ecology, habitat and threats. This is followed by a Surveillance Methodology, outlining measures that can be taken to monitor the species in such a way as to determine trends in population size, range or status. Further information is given on five species listed on Annexes II and V of the EC Habitats Directive.
